3 Claims.

This inventionrrelates to soda fountains and more particularly toimprovements in the drain lines thereof.

It is the usual practice in soda fountain construction to provide adrain line for draining liquids and water from various parts of thefountain, such as the refrigerated compartments or sections. In priorconstructions the drain line was open and permitted obnoxious gases toenter the compartments and sections with which the drain linecommunicated and also permitted the escape of cold air from thesecompartments or sections.

One o-f the objects of the present invention is to provide a sodafountain with a drain line of new and improved construction which issimple in design and can be economically manufactured.

Another object is to pro-vide a drain line for soda fountains which willprevent the escape of cold air from and the entrance of obnoxious gasesinto the fountain.

A further object is to provide a drain line for soda fountains whichwill permit a refrigerated compartment to be cleaned and flushed outwith water and yet will prevent the escape of cold air from thecompartment.

With the above and other objects in View, the present invention consistsin certain features of construction and combinations of parts to behereinafter described with reference to the accompanying drawing, andthen claimed.

In the drawing which illustrates a suitable embodiment of the invention,Y

Figure 1 is a transverse vertical section taken through a coldcompartment and syrup jar compartment of a soda fountain, showing thedrain line;

Fig. 2 is an enlarged section of the drain line and drain trap takenapproximately on line 2--2 of Fig. 1;

Fig. 3 is a section taken on line 3 3 of Fig. 2; and

Fig. 4 is a section taken on line 4 4 of Fig. 2.

Referring to the drawing in which like numerals refer to like partsthroughout the several views, the soda fountain selected forillustration comprises a body structure I having a refrigerated coldstorage compartment 2, and a refrigerated syrup jar compartment 3 whichcontains the syrup jars 4.

The syrup jar compartment 3 is provided with a drain line in the form ofa conduit 5 which extends downwardly through the cold compartment 2 asshown in Figure l. It is to be understood, of course, that the drainline may commuu nicate with other parts of the soda fountain.

The bottom portionof the body Iofthe foun-y tain is provided with anapertured depression 1 and the conduit 5 extends downwardly through theaperture with a clearance and into the interior of a hollow draincasting 8 lwhich isk surrounded by the insulation 9. The casting 8 abutsthe under side of the depressed portion and is held against the same bya threaded sleeve II) Ythreaded thereinto and having a flange II seatingagainst the upper side of the'd'epression 1. Fitting within the sleeveIB is a conical sleeve I2 which closely surrounds the conduit 5.

The interior o-f the casting 8 is formed with a pocket or cup IS whichis provided by a web I4 which extends upwardly above and around thelower end of the conduit 5 with clearance. The casting 8 is alsoprovided with a threaded outlet I5 outwardly of the web I4 and receivesan elbow I6 which carries a drain conduit I'I that extends through thebottom of the fountain and may be connected with a sewer or any suitablemeans for receiving the drain liquid.

Also, the drain line conduit is formed with a slot or .opening I8 in itswall, which opening is preferably slightly below the level of theinternal bottom wall of the compartment 2.

It will be noted in Figure 2 that the web I4 overlaps and surrounds thelower end of the drain line conduit 5 with clearance so that the conduitdischarges the water or. other liquid into the pocket or cup I3 with theresult that the water or liquid before it can discharge through thedrain conduit Il must rise above the lower end of conduit 5 and overflowthe web I4. Therefore, the

liquid draining through the conduit 5 forms a 1 liquid sealed trap whichwill prevent the cold air from passing through the drain and will alsoprevent obnoxious sewer gases from entering the soda fountain.

Furthermore, the compartment 2 through which the drain line conduit 5passes may be easily cleaned and flushed out with water by reason f ofthe opening I8 and yet the cold air will be retained within thecompartment.

Although a single embodiment of the invention has been herein shown anddescribed, it will be understood that numerous details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as dened in the following claims.

What I claim is:

1. In a soda Afountain cabinet having a refrigerated compartment, aliquid-receivingl cup disposed below the plane of the bottom of saidcompartment and arranged to overflow when full, a discharge conduit forreceiving overflow from said cup, an aperture in the bottom of said cm-5 partment communicating with the cup to permit the free flow of liquidsand gases through the aperture and cup, a removable drain conduitarrangeable in the compartment to extend through the aperture and haveits discharge end below the normal level of liquid in the cup to sealsaid conduit against the passage of gases, said conduit being closelysurroundable by the wall of the aperture to prevent the flow of liquidinto the cup except through the conduit, whereby the free flow of gasesthrough the aperture is prevented and the flow of liquid through saidaperture is restricted to the drain conduit.

2. n a soda fountain cabinet having a refrigerated compartment, aliquid-receiving cupI disposed below the plane of the bottom of saidcompartment and arranged to overflow when full, -a'discharge conduit forreceiving overflow from said cup, an aperture inthe bottom of saidcompartment communicating with the cup to Ypermit the free ow of liquidsand gases through the aperture and cup, a removable drain conduitarrangeable in the compartment to extend through the aperture and haveits discharge end below the normal level of liquid in the cup to sealsaid conduit against the passage of gases, said conduit being closelysurroundable by the wall of the aperture to prevent the ow of liquidinto the cup except through the conduit, whereby the free flow of gasesthrough the aperture is prevented and the ow of liquid through saidaperture is restricted to the drain conduit, and said conduit arrangedto carry waste liquids from other compartments than said rst namedcompartment through the aperture and into the cup. 5

3. In a soda fountain cabinet having a refrigerated compartment, aliquid-receiving cup disposed below the plane of the bottom of saidcompartment and arranged to overflow when full, a discharge conduit forreceiving overflow 10 from said cup, an aperture in the bottom of saidcompartment communicating with the cup to permit the free flow ofliquids and gases through the aperture and cup, a removable drain con-15 duit arrangeable'in the compartment to extend through the apertureand have its discharge end below the normal level of liquid in the cupto seal said conduit against the passage of gases, said conduit beingclosely surroundable by the 20 wall of the aperture to prevent the flowof liquid into the cup except through the conduit, whereby the free flowof gases through the aperture is prevented and the flow of liquidthrough said aperture is restricted to the drain conduit, 25 and thewall of said conduit having an opening therethrough arranged so thatwith the conduit in the aperture the opening is substantially at theplane Yof the bottom of the refrigerated compartment to permit liquid inthe bottom of 30 said refrigerated compartment to drain through theconduit.
